Front ultrasound sensorsSensors
Six ultrasound sensors in the front and rear
bumpers measure the distance to the closest
obstacle.
– Range of outer sensors
(front and rear):
approx. 24 in. (60 cm)
– Range of front middle sensors (arrow):
approx. 48 in. (120 cm)
Rear ultrasound sensors– Range of rear middle sensors (arrow)
(only in vehicles without spare wheel bracket):
approx. 59 in. (150 cm)
– Range of rear middle sensors
(only in vehicles with spare wheel bracket):
approx. 48 in. (120 cm)
Obstacles cannot be detected in the “blind” sen-
sor area (above and below the sensors).Maintenance Notes
fThe sensors must always be kept free of dust,
ice and snow in order to ensure that they are
fully functional.
fDo not damage sensors by abrasion or
scratching.
fMaintain sufficient distance when cleaning with
steam-jet units.
The sensors will be damaged if the pressure is
too high.

ventilated area.
fEnsure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially
cautious of such devices such as hot water
heaters which ignite a flame intermittently.
fBefore working on any part in the engine
compartment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
fBe alert and cautious around engine at all
times while the engine is running.
If you have to work on the engine while it is
running, always put the parking brake on and
put the gearshift lever in neutral or the
Tiptronic selector lever in position P or N.fIn particular, be very careful to ensure that

The fans can start or continue running as a
function of temperature, even with the engine
switched off.
Carry out work in these areas only with the
engine off and exercise extreme caution.
fYour Porsche is equipped with an electronic
ignition system. When the ignition is on, high
voltage is present in all wires connected with
the ignition system; therefore, exercise
extreme caution when working on any part of
the engine while the ignition is on or the engine
is running.
fAlways support your car with safety stands if it
is necessary to work under the car. The jack
supplied with the car is not adequate for this
purpose.
For vehicles with air suspension with level
control and height adjustment switch off level
control.
Please see the chapter “RAISING VEHICLE
WITH THE JACK” on Page 192.fWhen working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine can-
not be started.
Withdraw ignition keys (switch ignition off in
vehicles that have Porsche Entry & Drive).
fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher close at hand.
fIncomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your
authorized Porsche dealer.
Improper maintenance during the warranty
period may affect your Porsche warranty
coverage.
fSupplies of fluids, e.g. engine oil, washer fluid,
brake fluid or coolant, are hazardous to your
health.
